How to fix
The meter cannot recognize the
conductivity standard solutions.
1.
Make sure the probe is fully submerged in
the solution.
2.
Check if the standard solution is expired or
contaminated.
3.
Check if the conductivity electrode (two
black rods) is damaged.
4.
Check if the conductivity electrode is
contaminated. If so, please use a soft brush
with warm water to clean up.
5.
If none of the above, please contact us at
Is pressed before measurement is
fully stable ( comes up and stays)
Wait for to come up and stays on screen before
pressing
During calibration, readings being unstable
for over 3 minutes
1.
Shake the probe to remove the air bubbles
on the surface of the black rods
2.
Check if the conductivity electrode is
contaminated. If so, please use a soft brush
with warm water to clean up.
3.
Soak the probe in 12.88mS/cm solution for
10 minutes, then rinse with distilled water.
4.
If none of the above, please contact us at

Press key to turn on the tester. Press to switch to Conductivity measuring mode. Rinse the probe
in distilled water and remove excess water. Insert the probe in sample solution, shake it for a few seconds,
and allow it to stand still in the solution until a stable reading is reached. Get readings after comes up
and stays. Press to switch from conductivity to TDS, salinity, and resistivity.
